[Released] Wing42 Boeing 247D

Which is why I asked what the unit meant (, and how it would be used), because that’s quite a bit higher than the 1 gal/hr quoted as the sign the engine needs to be overhauled when I did that calculation myself.

Sorry, big typo in my numbers above. I’m in the process of editing. :slight_smile:

Me, too, I was using 64 oz / gal :roll_eyes:

But even at 128 oz / gal, that’s still 1.5 gal / hr, which is too high.

Except remember: that engine is NEVER pulling absolute max rated power except in extremis. Even most takeoffs would never use full manifold pressure/max RPM. So actual in-use operation, including cruise and descent, should result in much less than maximum oil usage.

Just had my first engine die on me after a few flights - not sure what went wrong as I had been keeping an eye on everything as usual. Could have been an iced up carb perhaps?

This brings me to the question of restarts; Are they possible? I unfeathered the prop after running carb heat for a bit in case it was some ice and got the fuel flowing to it again but no restart or even attempted restart. Not sure if it is possible or if there is a step I would have missed?

Just wondering if anyone has done it before or should I save my energy next time!

Restarts are a good question. I guess if you were at altitude and had enough speed, you could try it. So long as the prop isn’t featured, it continues to windmill. If you’re slowing for landing and don’t have much altitude, better just to land, I think.

The prop was windmilling with a good amount of RPM unfeathered (I was cruising with the left engine at 110mph). I wouldn’t imagine you need to dive and pick up too much speed as the mags should be firing and the cylinders are compressing. Not sure if it is modeled or whether the ‘meshing’ process is the only programmed way for an engine to start up.

Presently that’s not possible due to limitations of wwise and its implementation in msfs. It would also pose issues with drm / copyright for streaming/videorecording purposes.

I don’t know how it works on Twitch, but here’s typically what happens on YouTube. If you included copyrighted music in your videos, and IF the rights-holders have opted-in to YouTube’s revenue sharing system, your own video would be de-monetized by YouTube itself. Not a big deal for most casual gamers that just maintain a small hobby account with a few dozen to a few hundred subs. Once your channel is big enough to monetize (and that size gets bigger year by year due to the volume of streaming content out there), if your video has copyrighted music, you will NOT be credited with streaming revenue for your video, which can be a big deal for people who make money streaming. Fortunately, many bigger streamers have alternate money streams: Channel Memberships, Patreon, SuperChat donations, etc.

For the rest of us, what happens is, any streaming revenues and royalties the accrue from our videos gets divvied up by YouTube and split among the rights-holders for that music. Our videos do not get a “copyright strike,” which is nice, so we don’t have to take it down.

However, if the rights-holders are NOT part of the revenue-sharing deal with YouTube, you are subject to a copyright strike on your channel, which can be a bigger deal, potentially leading to your channel being taken down for repeat offenders.

Of course, this is just how it is today, for people in the circumstances above. Policies can and do change, and national and international agreements may be in play as well depending on where anyone lives.

Yeah I kinda guess it wouldn’t be possible to mod but 'twas just a nice dream. Also frankly the concerns of streamers don’t bother me as I don’t stream and anyway it’d only affect them if they chose to stream or record videos whilst using copyrighted music which would be their own fault so :man_shrugging:

What’s the word on mixture? I get that it’s full rich on startup, but I don’t see an RPM activity when I lean in flight . Any advice on this?

As you pull the mixture more and more lean, nothing should happen UNTIL at some point the RPM should drop quite suddenly. Then quickly rich a bit or you’ll cut the engines.

Typically 60% mixture at 4.000 ft but depending circumstances.

For landing back full rich I presume? Thanks for the answer, I didn’t lean that much out of fear in killing the engines

Actually, it is possible to mod, and, as long as you aren’t selling it or sharing it, copyright is not an issue.

I’m not saying it’s easy, but it is possible. There are WWYSE package unpackers out there. How you pack it up again with changed files is beyond my ken, however.

Okay, I can confirm that the radio is one of the things that doesn’t maintain its state. The music station I was tuned into last night was 560 kHz, (band IV I think?). This evening when I got into the plane, the radio had reset itself to Band I, but the frequency dial was correct once I changed the Band dial back up to Band IV.

The Battery switch also does not maintain state for sure. When I spawned in for my tests, the Battery switch was pushed in. I re-tuned the radio to the correct Band for the test mentioned above but I had no sound. I toggled the Radio On/Off switch, checked the Radio fuses, then opened the Battery switch and closed it again. When I did that, music sounded loud and clear once more.

So I had an observation a couple flights ago, and noticed the same thing tonight -

Has anyone else noticed that if you make abrupt changes attitude (roll, especially) that the oil pressure in one or more engines can change or oscillate? I was wondering if anyone who has monitored the sim variables through a telemetry/external control program has figured out if slosh in the oil sump is simulated? Or if pump performance varies based on aircraft G-loading? Remember, ideally, a perfectly coordinated 1G turn will still “feel” level to the aircraft, its systems, fluids, etc., so a sudden change in attitude will result in fluid slosh.

It mentions in the manual that you want to keep carb inlet temperature above 100F when in climb, cruise, or descent.

This might help you!

Fun fact I saw 4 reviews from 4 known YouTubers that highly praised the Add On but only one tried and failed a realistic engine start, the other 3 didn’t even tried.

It’s not THAT hard if people do the following:

  1. Pump up the fuel pressure BEFORE priming;
  2. Prime the engine 2 - 4 times, depending on OAT
  3. Have the engineer start cranking while wobbling up to 5+ PSI
  4. Set throttle at 25% - 30% (the 10% figure in the manual is a recipe for failure); full rich on the mxture;
  5. Mesh the gears
  6. Profit.

If at first you don’t succeed, prime again and repeat.

Yeah I managed to get it started a couple of times and I totally appreciate the challenge. I love that this plane exists in MSFS.
